## How do you calculate projectile motion with air resistance?

Mathematically, the resistive force represented by the vector F can be written as F=-f(v) u, where u=V/|V| is the unit vector along the direction of the velocity V. The minus sign guarantees that the air resistance acting on the projectile is always opposite to the direction of its velocity.

**What is projectile motion with air resistance?**

Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected near the Earth’s surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are passive and assumed to be negligible).

### How does air resistance affect projectile motion time?

Time of ascent; During ascent of projectile, both weight of projectile and air resistance act in downward direction.So, net acceleration in downward direction increases . Thus, time ascent decreases due to air resistance. The frictionless motion is based on v-horizontal = constant, and v-vertical = gt.

**Does a projectile experience air resistance?**

A projectile is a free-falling object. A projectile experiences negligible or no air resistance. A projectile must be moving in the downward direction. A projectile must be accelerating in the downward direction.

## Is air resistance ignored in projectile motion?

If air resistance is ignored , then there is no acceleration in horizontal direction in projectile motion. Hence the particle move with constant velocity in horizontal direction.

**How do you calculate air resistance?**

Air resistance can be calculated by taking air density times the drag coefficient times area all over two, and then multiply by velocity squared.

### When did Galileo discover projectile motion?

It is certain that Galileo discovered the parabolic trajec tory no later than 1608 and proved it mathematically early in 1609, although he did not mention it in print until 30 years later.

**How does air resistance affect motion?**

When air resistance acts, acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down. Air resistance depends on two important factors – the speed of the object and its surface area. Increasing the surface area of an object decreases its speed.

## What affects projectile motion?

FACTORS AFFECTING PROJECTILE MOTION There are three main factors that affect the trajectory of an object or body in flight: the projection angle, magnitude of projection velocity and height of projection.

**Which are examples of projectile motion?**

Examples of Projectile Motion

- Firing a Canon. When a cannonball is fired from a cannon, it does not move along a straight line, instead, it follows a curved path.
- Throwing a Basketball in the Basket.
- Sneezing.
- Javelin Throw.
- Archery.
- Water Escaping a Hose.
- Car and Bike Stunts.
- Golf Ball.

### When air resistance is taken into account while dealing with the motion of the projectile the quantity that increases is?

In the presence of air resistance, the range, maximum height, speed at which the projectile strikes the ground will decrease whereas the angle at which the projectile strikes the ground will increase.
